Abstract
The utility model discloses a power supply box casing which comprises a casing body and a panel. The casing body is a box-shaped body which is formed by deeply drawing an open inner cavity on one side. An integrated installation side extends out from the surrounding of the open side of the box-shaped body along the horizontal direction. Two longitudinal ends of the installation side are respectively provided with at least two casing body positioning notches. Two longitudinal ends of the panel are respectively provided with panel positioning notches corresponding to the casing body positioning notches. Flangings perpendicular to the panel respectively extend out from two longitudinal sides of the panel. The flangings are buckled on the open side of the casing body. The casing body positioning notches and the panel positioning notches coincide. The panel is fixedly connected with the installation side of the casing body through a number of fasteners. According to the utility model, the box-shaped body which is formed by deeply drawing the inner cavity is used; the production efficiency is improved; the manufacturing cost is reduced; four corners of a power supply box are filled with epoxy resin glues convenient for filling, which shortens the time of glue filling; the production cost of the whole power supply box is reduced; and the waterproof level of the power supply box is improved.
Description
Technical field
The utility model relates to a kind of supply unit, and especially a kind of housing of power pack belongs to technical field of electric appliances.
Background technology
Modern various compact electric apparatus equipment are owing to be subjected to the restriction of volume, external power supply box commonly used with civil power through the transformation rectification after the input electric equipment for its work, various small household appliances, notebook computer and LED light fixture etc. all use such power pack.Can epoxide-resin glue in the power pack that power panel and electronic component are housed plays the effect that sealed electrical source plate and electronic component prevent that it from making moist, and has improved the reliability of power pack work.The LED lamp power box of outdoor use expose to the sun and rain, long-term work under the comparatively adverse circumstances of variations in temperature great disparity, must durable in usely could satisfy instructions for use.This power pack housing adopts sheet metal laterally to be bent into the U-shaped body of side opening, form with the end plates sealing respectively at vertical two ends of U-shaped body then, because the junction right angle intersection of end plates and U-shaped body, the epoxide-resin glue of can is difficult to be full of four jiaos of power pack, influences the filling quality of epoxide-resin glue.In order to make epoxide-resin glue four jiaos of flowing to power pack as much as possible, must prolong the filling time, thereby reduce operating efficiency.The manufacturing process of assembled power pack is many, and cost is higher, and rainwater infiltrates in the power pack from the junction of end plates and U-shaped body easily, has shortened the useful life of power pack.
Summary of the invention
The novel purpose of this usefulness provides a kind of simple in structure, low cost of manufacture, power pack shell that the epoxy resin filling quality is good.
The utility model is achieved by the following technical programs:
A kind of power pack shell, comprise housing and panel, described housing is that a side is opened wide the box body that the inner chamber deep drawn is shaped, along continuous straight runs extended the installation limit that is connected around described box body opened wide a side, vertical two ends on described installation limit are respectively equipped with at least two housing locating notches, and the vertical two ends of described panel are respectively equipped with and housing locating notch corresponding panel locating notch; The vertical both sides of panel are extended the flange perpendicular to panel respectively, and described flange is fastened on the unlimited side of housing, and housing locating notch and panel locating notch overlap, and panel is fixedlyed connected by several securing members and housing installation limit.
The purpose of this utility model can also further realize by following technical measures.
Aforesaid power pack shell, wherein in the housing of box-like between each adjacent surface, all be connected by round-corner transition between panel inboard and the flange.
Aforesaid power pack shell, the radius of corner R of wherein said fillet is 2.5～3.5mm.
The box body that the utility model adopts the inner chamber deep drawn to be shaped replaces the box body that assembly unit is shaped, and has improved production efficiency, has reduced manufacturing cost.Connect by round-corner transition between each adjacent surface in the box body of the present utility model, the epoxide-resin glue of being convenient to can is full of four jiaos of power pack, has shortened the encapsulating time, has saved human cost, thereby reduce the production cost of whole power supply, and improved the waterproof rank of power pack.The utility model is convenient to dismantle, and has made things convenient for formed product detection and maintenance afterwards, also is beneficial to product simultaneously and uses collective's recovery later to disassemble recycling, has significantly promoted the product economy benefit.
Advantage of the present utility model and characteristics will illustrate by the non-limitative illustration of following preferred embodiment and explain that these embodiment only provide as an example with reference to accompanying drawing.
Description of drawings
Fig. 1 is housing stereogram of the present utility model;
Fig. 2 is panel stereogram of the present utility model;
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment as depicted in figs. 1 and 2 is the power pack shell of outdoor use LED lamp, and the utility model is not limited to this embodiment, also comprises the power pack shell of other purposes.
Present embodiment comprises housing 1 and panel 2, housing 1 is that a side is opened wide the box body that the inner chamber deep drawn is shaped, along continuous straight runs extended the installation limit 11 that is connected around described box body opened wide a side, vertical two ends on described installation limit are respectively equipped with two housing locating notches 12, and panel 2 vertical two ends are respectively equipped with and housing locating notch 12 corresponding panel locating notches 21.Panel 2 vertical both sides are extended the flange 22 perpendicular to panel 2 respectively, the flange 22 of panel 2 vertical both sides is fastened on the side that housing 1 opens wide, housing locating notch 12 and panel locating notch 21 overlap, the trip bolt that is positioned on 2 four jiaos of the panels passes panel hole 23 and housing bore 13 respectively, panel 2 and housing is installed limit 11 fixedly connected and be integral.When power pack is installed, panel 2 can be placed on the mounting plane down, by the trip bolt that passes housing locating notch 12 and panel locating notch 21 the utility model be fixed on the mounting plane.Wherein in the housing 1 of box-like between each adjacent surface, panel 2 inboard with flange 22 between all the round-corner transition by radius of corner R=3mm be connected.
In addition to the implementation, the utility model can also have other execution modes, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection range of the utility model requirement.
